To all whom it may concern:

Be it known that I, WIL IAM H. BAKER, a

citizen of the United States, and a resident of Central Falls,Providence county, State of Rhode Island ,have invented certain new anduseful Improvements in Picture and Sound Reproducing Apparatus, of whichthe following is a specification.

The present invention has for its object to combine a kinematograph orsimilar apparatus for exhibiting pictures in which the 1m- ;pression isgiven to the eye of objects in motailed views.

tion with a graphop'hone or similar soundreproducing apparatus in suchmanner that the two devices or sets of apparatus shall be operated insynchronism. v I y In an ap lication filed by me February 6, 1904, SeriaNo. 192,311, I have described a kinematograph in which the pictures arearranged in a spiral or helical path upon a glass or other suitable diskand the disk rotated intermittently in front of a lantern-lens and atthe same time moved toward or away from the optical axis of the lens ata uniformly-varying rate of speed. For the purose of illustrating thepresent invention I ave shown a kinematograph similar in constructionand mode of operation as that described in my said application and havecombined therewith in carrying out the present invention a graphophoneor similar soundreproducing apparatus of any well-known t e.

'Ihe invention will be understood'by reference to the accompanyingdrawings, in which- Figure 1 is a side elevation of one embodi ment ofmy invention; Flg. 2, a front view,

and Fig.3 a to view. In these three fig ures certain of t e parts arebroken away for the sake of clearness. Fig. 4 is a side view of therack-disk, and Figs 5 and 6 are de- Similarv reference-numerals indicatesimilar parts in the several views. I

Referring to the drawings, the numeral 1 designates a framework u onwhich is mounted the parts hereinafter escribed.

2 designates a box or casing inclosing the motor or other drivingmechanism of a soundreproducing apparatus adapted to drive thesound-record 3 in a well-known manner.

4 designates the sound-horn, which may be supported upon a bracket 5.

'vance laterally the 6 designates a lantern of any well-known typehaving a lens 7.

8 designates a picture-disk ada ted to be rotated and advanced laterallin ront of the lens 7. The pictures upon t is disk consist ofphOtographically-produced positives with a black or opaque ground. Thedisk is of glass or celluloid and may, if desired, be clampedbetweensuitable plates, and the pictures are arranged thereon in aspiral or elical path, as indicated by the broken line 9 in Fig. 2, afew of the. pictures being indicated by circles. By assembling thepictures in this manner a very large number may be contained in a smallcompass, overcoming many objections incident to the generallyusedcontinuous films, and partlcularly in that agreater number of picturesmay be exposed per unit of time than is practically possible with afilm, thus giving a better-defined and more life-like impression uponthe eye.

In the present instance I utilize the motor of the sound-reproducingapparatus to rotate thesound-record and also to rotate andadicture-disk. This is accomplished by the ibllowing means: 10designates a shaft of the motor inclosed within the casing 2, and 11 agear-wheel secured to said shaft, said gear meshing with a gearwheel 12on a shaft 13, which projects outside of the casing 2 and has a bearingin the framework. Secured to the shaft 13 is a spurgear 14, meshing witha similar gear 15, se cured on a shaft 16,- having suitable bearings inthe framework. Upon the other end of the shaft 16 is secured a spur-gear17, meshing with a similar gear 18 on the shaft 19, which shaft carriesa single-toothed pinion 20, constituti'ng one member of a well-knownform of stop-motion. Mounted on the shaft 21, which shaft is parallelwith the shaft 16, is the second member 22 of the stop-motion. Themember 22 is in the form of a wheel provided with radial recesses 23 inthe periphery thereof, (see Fig. 5,) adapted to be engaged by the tooth24 ofthe pinion 20 to impart to said Wheel an intermittent rotarymotion. The shaft 21 extends across the center of a disk 25 and carriesat its other end a toothed wheel 26, having as many teethithereon" asthere are notches or recesses in the wheel 22 of the stop-motion. Thedisk:25, which-is preferably of metal, is perforated or recessed toothedwheel engaging successive perfora-- tions or recesses 27 when said wheelis intermittently rotated through'the train of gearing above described.The disk 25 is,in effect, a rack-disk, and it is obvious that acontinuous rack having teeth to cooperate with a proper gear or pinionmay be used. The intermittent rotary motion of the disk 25 istransmitted to the picture-disk 8 through the shaft 28, on which bothdisks are mounted. Said shaft 28 is mounted in bearings 28, which formpart of a swinging frame comprising side arms 29, pivotally mounted at29 on a shaft 30, having bearings in the framework. The side arms 29 areconnected by. a suitable web 31. i A collar 30 is secured to the shaft30, and between said collar and one of the bearings 29 is a spring 32,which serves to hold the disk 25 up against its driving wheel 26.

Not only must a rotary motion be imparted to the picture-disk 8, butsaid disk must be advanced toward the optical axis of the lens, and thislatter movement is effected by the following means: On the outer end ofthe shaft 13 is a pinion 33, which meshes with a wheel 34 on a shaft 35,which shaftcarries a worm 36, meshing with a wormwheel 37 on a shaft 38,having bearings in the framework. On the ends of the said shaft 38 aremounted two constant-progression cams 39, which are adapted to bearagainst rollers 40, mounted on studs midway of the length of the sidearms 29 of the swin ing frame.

The operation of the mec anism so far described is as follows: Therotary motion of the gear 11 by means of the motor within the casing 2is communicated through-the gears 12, 14, 15, 17, and 18 to thesingle-toothed pinion 20, and b the latter an intermittent rotary motionis imparted to the rack-disk 25 and a corresponding movement to thepicture-disk 8. As'the perforations or recesses in the disk 25correspond in arrangement, po-

sition, and number to the pictures on the disk 8, it is obvious thatcite engagement of a tooth on the wheel 26 with a perforation or recessin the disk 25 will impart an intermittent rotary movement to said diskand will bring a picture on the disk 8 into and allow the same to remainin the illuminated field for an interval of time, the interval ofexposure necessarily being greater than the time required to effect achange from one pictureto another, owing to the employment of thedescribed stop-motion 2 0 22. Simultaneone with the intermittent rotarymovement 7 th'eswinging frame is moved and in consequence thepicture-disk 8 is advanced later ally across the optical axis of thelens through the action of the cams 39 onthe rollers 40. This lateralmovement is uninterrupted and at a uniformly-varying rate'of'speed. Inthe position shown in the drawings the exposure is begunwith thepictures on" the outer convolution of the spiral, so that for every unitof angular advance'of the cams 39 the disk 8 is advanced a unit oflateral movement. The contiguous convolutions of the spiral are placedas near as possible to each other to save space, and the cams 39 are soconstructed that for each complete rotation of the disk 8 said disk willbe advanced laterally a distance equal to the distance betweencontiguous convolutions of the spiral or a distance equal to thediameter of one picture, if the pictures are so disposed that those oncontiguous convolutions contact with each other. For example, if thedistance between two contiguous convolutions of the spiral is onequarterof an inch then the disk 8 will be advanced that distance for eachconvolution of the spiral or for each complete-rotation of the disk 8.When beginnin at the outer end of the s iral, every unit 0 advance alongthe spira that is, from the center of one picture to the center of thenext succeeding pictureinvolves avarying angular speed of the disk 8 dueto the approach of the spiral toward its center. This angular speedincreases and because the progress of the spiral toward the center isconstant, owing to the particular stop-motiori,therefore the increase ofthe angular speed of the disk 8 will be uniforml accelerated, but thetime of ex osure w' 1 be constant. If the pictures shou ld be arrangedon the disk 8, beginning at the center of the spiral, it is obvious thatthe angular speed of rotation would be uniformly decreased in travelingto the outermost convolution and that the axis of said disk would bemoved away from the optical axis at a uniformly.-

varying rate by the constant-progression earns 39. Such changes in thedescribed mechanism to meet the condition in which the pictures arearranged, beginning at the center of the spiral, areobvious. When aseries of ictures has been exhibited and the end of t e spiral reached,the disk Swill have been advanced until the last picture is in line withthe optical axis of the lantern-lens and the swinging frame will havereached the limit of its movement. In order to return the frame to itsinitial position, I provide a lever 41, pivoted on the framework andhaving one arm 41' engaging one of the bearings 29-of the swingingframe, as shown in 1. By depressing the outer end of lever 41 the entireswingingframe. carrying the icturedisk 8-, came 39,-&c.' will be movedorward or in thedirection of the screen. The effect of this to releasethe rack-disk 25 from enagement with its driving-wheel 26 and to reeasethe worm-wheel 37 from engagement dis with the worm 36. This ermits thespring 42, secured at its ends to f red collars on the shaft 38, torotate the shaft 38, thereby returning the cams 39 to their initialposition and also permitting the frame'to bers wung on its pivotalsupports 29- to restore the picture- 8 and the rack-disk to the startingpo. sition. r x

' Any suitable means may be employed to secure the picture-disk on theshaft28 and to permit the ready removal of one disk and its replacementby another. As shown in the drawings, the lens 7 of the lantern ismounted upon a standard 44, supported upon-a bracket 45, secured to theframework. A slot in said bracket permits the standard 44 and lens 7 tobe swung forward to allow of easy access for removingand replacing thepicture-disk. A'set-screw 46 or other means may be employed toretain-the standard in position.

Inasmuch as the present apparatus is designed for use with a hotographicpicturedisk having the groun black or opaque and as the period of changefrom one picture to the next on the disk is so infinitesimal as not tobe perceived by the eye, there will be nonecessit .for the use of ashutter. If,.however, this is found necesssary, any of the wellknownforms of shutters may be used.

While I have described my invention in connection with an apparatus forrojecting a picture upon a screen, it is to e under stood that themechanism may be mounted in a suitable casing, so thatthe ictures fixedupon the disk may be viewed directly by the eye, as in well-known typesof mechanismyof this class, and such mec anism may be connected up withthe sound-reproducing a pa-' ratus, so as to operate the two in syncronism.

' One drawback to the enjoyment of a icture-exhibiting apparatus aloneor o a sound-reproducing apparatus alone is that but one sense isafl'ectedthat is, either the sight or the hearing. In viewing thereproduction of an animated scene the absence of the sounds accompanyingthat scene detract materially from the enjoyment. invention makes itpossible to convey to the senses not only the action of a public speakeror of a traveling railway-train, but the actions of a speaker may beaccompaniedby a reproduction of his'voice and words, or the movement ofthe train maybe accompanied by the noises made. by the train, givingthereby 1.
